I was hoping that someone would post an xsl solution before I offered my
solution. I think your problem results because you have a somewhat poorly
constructed xml document.

I wrote a little perl script that changes your original document from this:

<pardef id="2" leftmargin="0.3938in" tabs="L1.1806in L1.6729in L1.7715in
 L2.5590in L2.9521in"/>

To this:

<pardef id="2" leftmargin="0.3938in" tab1="L1806in" tab2="L1.6729in"
tab3="L1.7715in" tab4="L2.5590in" tab5="L2.2952in" num_of_tabs=5/>

I have made the script generic, so it could split any string in any tag. You
just provide the name of the tag, the attribut you want to split, and the
delimter (whether it is a space, or a capital "L" or what.) I could also put
in an extra two lines to strip the "L" and the "in" from the above strings.

The script is small, and if you have perl on your system, I can send it
along. That way, you have the information you need in an attribute, and you
just have to pick out this info to make your fo object.

Of course, you might not have perl. I know it is better to use xsl for
tranformations (especially on an xsl mailing list!), but sometimes pre-perl
processing can really simplify an xsl stylesheet.
